This invention arelates .generally eto. sellers pertains particularly toimprovements in-- hand oilers or oiling "cans;

The present invention :hastfor' its .principal object to "provideanximproved.oiling can which is designed :in such a manner :as to:makepossible the. easy ejection offoilywhen the-.caniis nearly empty,with the can in aspartly or fully invertedotherwords,,to.holdthecanentirely upside down.

If it is necessary toholdthe can partly inverted the small quantity ofoil inthe can will settle in the-lowestflpart below theinlet end ofthe-spout so'that; the. oil cannot. be ejected.

The present invention isdesigned to facilitate the ejection of all ofthe oil from the can when only -a;small quantity ofioilaremains, eventhough the can, maybe .inverted only part way, by-the provision of anoil trapping means at the angle formed between the bottom and the sidewall of the can so that such oil as gathers in the low part of the canor receptacle when the can is only partly inverted, can be forced to andout through the can spout.

The invention will be best understood from a consideration of thefollowing detailed description taken in connection with the accompanyingdrawing forming a part of the specification, with the understanding,however, that slight changes or modifications may be made in thestructure without departing from the spirit of the invention so long assuch changes or modifications are within the scope of the appendedclaim.

In the drawing:

Figure 1 is a view partly in side elevation and partly in verticalsection of an oil can constructed in accordance with one embodiment ofthe present invention.

Figure 2 is a sectional view partially through the lower part of thereceptacle, taken on the line 2-2 of Figure 1.

Figure 3 is a view partly in side elevation and partly in section ofanother embodiment of the invention.

Figure 4 is a partial sectional view taken substantially on the line 44of Figure 3.

Referring now particularly to the drawing, especially Figures 1 and 2thereof, the numeral 2 I0 generally designates a "receptacle of the:usual form .or design, having. the outwardlyfbowed bottom. wall I Iwhich is. resilient and 'functions as apumping diaphragmtoforce .theoilfrom within the receptacle. .Suchhand oilers have the-side wall I2tapered to thetcircular neck Ildefiningthe outlet opening forthereceptacle -and suchneck is provided with suitable screwthreadsfilto: facilitate the attachment Itheretoofthe cap Ill.

In the construction shown in Figure "-1, broken threads I-5 areillustrated, such typeofthreadbeing particularly desirable when it isrequired" that the cap M. be connected with the heck-"I3 withaminimumaof rotation. However, 'itis :to, be understood-that theinvention is not limited to the use of this .particulartype of thread asany otherzsuitableconnecting means between thecap. and" the neck. may beemployed.

Attached at one end to and" openingthroug'h the central part of' 'thecap M; is the spout Ii which is straight throughout. the majorportion-of its length and disposed upon the-axial centerofi' thereceptacle I I]; Atxits: outer: end the spouti'has the laterallycurved/discharge tip ILL the particular purpose off whichwillabehereinaftermore fully described.

At its inner end there is connected with the spout, one end of a tube I8which is bent to provide the obliquely extending portion I9 whichterminates in the short straight inlet tip 20. The length of the tube I8is such that when the cap I4 is threaded tightly onto the neck I3, theinlet tip 20 will lie in close proximity to the bottom of the can and tothe side wall thereof or, in other words, the inlet tip will lie in thecorner or angle formed between the bottom and the side wall.

Means is provided at the inlet tip of the tube I8 to form a trap whichis designated 2| and in the embodiment of Figure 1 this trap is providedby securing to the inner side of the wall I2 a plate or web 22 whichextends downwardly and inwardly toward the bottom I I, leaving justsufficient space between its free inner edge 23, and the bottom of thecan, for the tip 20 to extend thereunder. Thus the inlet end of the tip20 is entirely within the oil trap 2|.

The terminal inlet tip 20 of the tube I8 extends in the same directionas the outlet tip I1 of the nozzle and the pitch of the threads I 5 issuch that when the cap I4 is screwed down tightly upon the neck I3 thetip 20 will be brought into position beneath the web 22 or in the oiltrap. Thus when the can is tipped or turned onto its side for thepurpose of ejecting oil from the dis-Q.

charge tip l'l, if the oil is low in the can it will collect or becaught in the trap 2| where the inlet end of the tube l8 lies and thuswhen the bottom is forced inwardly to create the necessary internalpressure for ejecting the oil through the nozzle, the trapped oil willbe discharged into the tube I8 and forced through the nozzle.

Another embodiment of the invention is illustrated in Figures 3 and 4.In this construction the receptacle is generally designated l0 and thecap and nozzle are the same as in the form shown in Figure 1 and neednot, therefore, be specifically described.

In this embodiment the tube l8, which carries the oil from the bottompart of the receptacle to the discharge spout, has the obliquelydirected portion I 9' which is in the same relation with the tip of thespout as the portion IQ of the structure shown in Figure 1, but the oiltrap forms an integral part of the inlet end of the tube, such trap herebeing generally designated 24. This trap 24 is in the form of aninverted receptacle 25, which forms an integral part of the end of theoblique portion IQ of the tube and is shown as being of circular designalthough any other form or design may be employed.

The open side of the receptacle 25 is directed downwardly toward thebottom of the receptacle I 0' and is in close proximity thereto as shownin Figure 3 in addition to being disposed closely in the angle betweenthe can or receptacle bottom and side walls.

It will be seen from the foregoing that the action of the embodiment ofFigures 3 and 4 will be the same as that of the embodiment of Figures 1and 2 which is that when the receptacle is partly inverted and is onlypartly filled with oil or the oil level has dropped to a very low pointwhere the receptacle is practically empty, such oil will collect in thecorner between the side and bottom walls and when the can is in theproper position for discharging from the nozzle tip, the collected oilwill be received in the trap 24 from which it can be readily ejectedwhen the bottom wall of the can is pressed inwardly.

From the foregoing it will be readily apparent that an oil canconstructed in accordance with the present invention provides meanswhereby practically the last drop of oil may be ejected therefrom eventhough it may not be possible to completely or entirely invert the canas is necessary in those types of oil cans where complete inversion isrequired to get the last bit of oil into the cap for discharge into thenozzle.

I claim:

A liquid dispenser of the character stated, comprising a receptaclehaving a bottom and a side wall which tapers to a central top opening, aspout connected with said opening, a tube connected at one end with theinner end of the spout and extending downwardly and laterally in thereceptacle and terminating in a short straight inlet tip portion havingits end relatively close to the side wall of the receptacle and in theangle between said side wall and the receptacle bottom, and meansforming a liquid: trap at the inner end of the tube, with which the saidend of the inlet tip portion is in communication, the said trap com-'prising a web extending transversely of and attached to the receptaclewall and having a free edge in spaced relation with the bottom wall andextending across the top of and spaced from said tip portion, the. saidfree edge of the webbeing the same distance throughout its length fromthe receptacle bottom Wall whereby the tip portion may be shifted ineither of two directions horizontally from beneath the web.
